The ROW ID bit does not touch ANY other portion in the JBoss source except
for
a) Generating SQLs
b) Setting parameters.
Options A,B and C should work as usual, correct me if I am wrong. As for
option D, I am suprised that it has become part of our 'standard' commit
options. I wrote some code and never had a chance to commit it and unless
someone else has commited stuff for option D let me know and I'll have to
commit the code!
